High-efficiency dej reducer yog tshuaj lom neeg cov khoom siv dav siv hauv kev sib xyaw ua ke tsim. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhim kho cov dej ntws thiab plasticity ntawm cov pob zeb los ntawm kev txo cov dej-cement piv tsis cuam tshuam rau lub zog thiab kav ntev ntawm cov pob zeb.
1. Txhim kho qhov compactness ntawm pob zeb
High-efficiency dej reducer txhim kho lub compactness ntawm pob zeb thiab txo porosity los ntawm kev txo cov dej sib tov. Cov txheej txheem ntom ntom tuaj yeem tiv thaiv kev nkag mus ntawm cov khoom tsis zoo sab nraud (xws li dej, chloride ions thiab sulfates, thiab lwm yam), yog li txhim kho impermeability thiab te kuj ntawm cov pob zeb. Kev txhim kho compactness kuj tseem tuaj yeem txo cov dej pore hauv cov pob zeb, txo qhov kev nthuav dav uas tsim los ntawm cov dej khov ntawm cov dej pore thaum lub voj voog khov-thaw ntawm pob zeb, yog li txo qhov khov-thaw kev puas tsuaj.
2. Txhim kho cov tshuaj erosion tsis kam ntawm pob zeb
High-efficiency dej reducer tuaj yeem txhim kho cov tshuaj erosion tsis kam ntawm pob zeb. Qhov no yog vim hais tias cov pob zeb ntom ntom ua rau nws nyuaj rau cov tshuaj phem kom nkag mus rau hauv cov pob zeb, yog li ua kom cov txheej txheem ntawm cov tshuaj yaig. Piv txwv li, nyob rau hauv ib puag ncig uas muaj cov tshuaj chlorine, qhov nkag mus ntawm cov tshuaj chloride ions yuav qeeb, yog li ncua lub sij hawm ntawm steel corrosion thiab txhim kho lub durability ntawm cov pob zeb muaj zog.
3. Txhim kho qhov tawg tsis kam ntawm pob zeb
Txij li cov dej ua kom muaj txiaj ntsig zoo tuaj yeem txo qis cov dej sib xyaw, qhov shrinkage tus nqi ntawm cov pob zeb, tshwj xeeb tshaj yog cov yas shrinkage thiab drying shrinkage, yog txo. Qis shrinkage txo qhov kev pheej hmoo ntawm pob zeb tawg, yog li txhim kho tag nrho cov durability ntawm pob zeb. Qhov kev txo qis ntawm cov pob zeb tawg tsis yog tsuas yog muaj txiaj ntsig zoo rau kev zoo nkauj thiab kev ncaj ncees ntawm cov qauv, tab sis kuj txo qhov kev pheej hmoo ntawm cov khoom tsis zoo sab nraud nkag mus rau hauv cov pob zeb los ntawm cov kab nrib pleb.
4. Txhim kho cov cuab yeej cuab tam ntawm pob zeb
High-efficiency dej reducers tuaj yeem txhim kho lub zog thaum ntxov thiab lub zog ntev ntawm cov pob zeb, uas muaj kev cuam tshuam tseem ceeb rau kev ua haujlwm ntawm cov pob zeb ua vaj tse. High-strength pob zeb muaj tsawg deformation nyob rau hauv lub sij hawm ntev load, zoo tawg tsis kam, thiab muaj peev xwm tiv taus qhov yaig ntawm ib puag ncig yam tseem ceeb. Tsis tas li ntawd, lub zog ntxov dua tuaj yeem pab txo lub sijhawm kho, ua kom cov kev tsim kho kom zoo, thiab txo cov nqi tsim kho.
5. Kev cuam tshuam ntawm carbonation qhov tob ntawm pob zeb
Cov nyhuv ntawm high-efficiency dej reducers ntawm carbonation qhov tob ntawm pob zeb yog qhov nyuaj dua. Ntawm ib sab, cov dej reducers txhim kho qhov compactness ntawm pob zeb, ua rau nws nyuaj rau cov pa roj carbon dioxide nkag mus, yog li ua kom cov pa carbonation qeeb; Ntawm qhov tod tes, vim cov nyhuv ntawm cov dej txo qis, tej zaum yuav muaj qee qhov tsis tiav hydrated cement hais hauv cov pob zeb, uas yuav ua rau qee qhov pores thaum lub sij hawm tom qab hydration, uas yuav ua rau kom qhov tob ntawm carbonation. Yog li ntawd, hauv kev siv tswv yim, nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog ntau yam thiab siv cov khoom siv dej kom tsim nyog.
6. Txhim kho qhov Frost tsis kam ntawm pob zeb
High-efficiency dej reducers tuaj yeem txhim kho Frost tsis kam ntawm pob zeb. Qhov no yog vim cov dej reducers txo cov dej sib xyaw hauv cov pob zeb, yog li txo cov dej dawb hauv cov pob zeb. Nyob rau hauv qhov kub thiab txias ib puag ncig, qhov khov ntawm cov dej dawb yuav ua rau lub ntim nthuav dav, yog li ua rau pob zeb tawg. Kev siv cov dej ua kom muaj txiaj ntsig zoo txo qis cov ntsiab lus ntawm cov dej dawb, yog li txo qhov kev puas tsuaj rau pob zeb los ntawm kev khov-thaw mus.
High-efficiency dej reducers ho txhim khu lub durability ntawm pob zeb los ntawm kev txhim kho lub compactness, tshuaj corrosion kuj, tawg kuj thiab Frost tsis kam ntawm pob zeb. Txawm li cas los xij, hauv cov ntawv thov tshwj xeeb, cov dej txo qis yuav tsum raug xaiv kom tsim nyog thiab siv raws li kev xav tau ntawm engineering thiab ib puag ncig kom ua tiav cov txiaj ntsig zoo tshaj plaws. Nyob rau tib lub sijhawm, kev sim tshuaj ntsuam xyuas tsim nyog yuav tsum tau ua kom ntseeg tau tias kev siv cov dej ua kom muaj txiaj ntsig zoo tuaj yeem txhim kho qhov ua tau zoo ntawm cov pob zeb.
